Jani Nikula 7af03e6887 drm/probe-helper: warn about negative .get_modes() ...

The .get_modes() callback is supposed to return the number of modes,
never a negative error code. If a negative value is returned, it'll just
be interpreted as a negative count, and added to previous calculations.

Document the rules, but handle the negative values gracefully with an
error message.
